Letters Patent No. 79,300, dated June 30, 1868.

IMPROVEMENT IN HARVESTERS. j

TO ALL WHOM IT MAY CON GERN:

Be it known that I, DARIUS BABCOGK, of Warsaw, in the county of Hancock,and State of-Illinois, have invented a new and improved Mower an'dReaper; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanying drawingsforming part of this specification.

This invention relates to anew and improved method of constructingmachinery for mowing and reaping,

whereby the same is more economically done, and whereby, also, themachines are made more certain in their action, and are rendered moredurable and less likely to get out of repair. i It consists of acircular frame, supported by an axle and wheels in the ordinary way,upon which said axle is a bevelled-gear wheel, engaging with abevelled-gear pinion on a vertical shaft supported by said frame;

Upon said shaft is a crown-geared wheel, engaging with a pinion onahorizontal shaft, also supported bysaid frame, to which said horizontalshaft a wheel and crank are attached, by means of which the cutters areoperated. i 7

It consistsalso of a frame pivoted to the axle, operated by a lever. Tosaid frame is attached a chain, which said chain is attached, by theother end of the same, to an arm, which supports the flexible bar of themachine, so that the same may be raised when necessary.

It consists also of a hook, attached to a brace on an arm on saidcircular frame, so constructed and arranged as to prevent the flexiblebar of the machine from rolling up, and also to serve as a guide for theflexible bar of the machine when the same is folded up on the machine. 7

The difference between a machine for mowing and reaping, having myimprovement, and the machines now in common use, consists in thearrangement of the gearing in connection with the driving-wheels of themachine, and the hook attached to the frame of the machine, for thepurpose above specified, and in the frame for raising the flexiblebar'of the machine from the ground.

In the accompanying plate of drawings' Plate 1 is a plan view of myinvention. Plate 2 represents a central vertical side section of thesame, taken in the line in a:, plate 1. Similar lettersof referenceindicate corresponding parts. Upon the axle M, and rigidly secured tothe same in a horizontal plane, is an annular frame, P, said frame Pbeing provided with an arm, P, extending-outward and beyond one of thewheels W, as shown in the drawing, plate 1, to which \is secured thebrace b, said brace b extending from the end of the arm 1? to one end ofthe axle M, by means of which said brace b said arm P is'strengthenedand protected.

Said frame P is also provided with another arm, V, so constructed as toreceive the pole or tongue, by means of which the entire machine isdrawn, said pole or tongue being secured to the arm V, so as that the-same may be readily removed. I

Upon said frame P, so as to coincide nearly with thesame, is bolted, bythe bolts e, the dome-shaped frame A. Said frame A consists of acircular flange, to which are attached four or more inclined braces orsupports, terminating at the top in a circular solid piece, 6, saidflange, and said braces, and said piece 6, being cast in anf 'rece, soas to form a frame in the shape of a' dome or truncated cone, as shownin the drawing, said piece I: being provided with a screw-thread, so asto receive the nut- 7t, as shown.

Across the frame F, and on the under side of the same, extending fromone side of said frame to the other, through a diameter of said frame P,is a cross-bar or support, K. i I

Said cross-bar K is bent, so as to pass over the axle M, so as not totouch the same, said cross-bar K being provided with an upright orstcpto receive the lower end of the vertical shaft B, said upright being onthe centre of said cross-bar, and directly over the axle M, as shown.

Upon the vertical shaft B, and near the upper end of the same, and keyedsecurely thereto, in the ordinary way, is the crown-wheel a.

Said crown-wheel a is a geared wheel, slightly bevelled, having adiameter as great as will turn within the frame A, and conforms inshape, as shown in the drawing, to the frame A.

Upon the shaft B, and directly under the attachment of the crown-wheelate the same, is a bevelled-gear pinion, C, secured to the shaft B witha key in the ordinary way, having the teeth on the under side of thesame,.as shown.

Upon said axle M, and near one end of the same, and keyed to the same nthe ordinary way, isthe bevelledgear wheel 1), having its teeth on theside of the same towards the pinion C, and fittinginto the same, in theordinary way of changing a horizontal to a vertical motion.

Said wheel is of such diameter as that it will rotate within therim ofthe crown-wheel a, and so that ,the rim of the crown-wheel a willrevolve about its centre without interfering with the wheel-D.

Over the frame A is the dome A, which is held down into its place by thenut n, fitting upon the screwthread on the part b of frame A, as shown.i The shaft B is supported at its upper end by the piece 6 of the frameA.

Upon the frame P, and secured to the same by the screw 0, is a support,F, provided with suitable boxes to receive the journal on one end of theshaft H, and in which said boxes said shaft H turns.

Upon the opposite side of the frame I, and at the rear of the machine,and secured to said frame 1? by suitable bolts, is a frame or support,F, upon which said frame, and in such'a way as to allow the shaft H aslight inclination downward and forward, are suitable boxes or bearingma, andin which said boxes a the shaft H turns.

Upon said shaft H, and near the back end of the same, is a gearedpinion, E, slightly bevelled, so as to fit into the crown-wheel a, asshown, by which saidcr'own-whe'el a and-said pinion E said shaft H isdriven in the ordinary way of changing the motion of a vertical shaft toa shaft slightly inclined from a horizontal line.

Upon the other or front end of the shaft H, and keyed thereto in theordinary way, is' a wheel, G.

In the wheel G, and secured thereto in the ordinary way, at a distancefrom the centre of the same equal to the len th of motion re uired'forthe cutters is the cranl in a b means of which and the connectin -rod bq p 7 y c;

a the cutters in the flexible bar of the machine are driven in theordinary way, as shown."

Through an eye in the end of the brace Z1, whichis secured to the arm I?of the framed is pivoted the hook g, extending from the said eyeforward, where it is pivotedt'o the bar near the point where theflexible bar-R is pivoted to the same, and extending forward stillbeyond the point of the attachment of the same to bar 2',

where it terminates in a hook bent downward, the point orend of whichreaches-down on to shoe in such a way as shown in the drawing, as toprevent said flexible bar from lifting or rolling up.

Said'hoolt 9 having also the purpose of guiding the flexible bar R, sothat the same may be at any time folded up without'adjustin'g thecutters as now. I

Upon the axle M, and upon the. same end of the machine as the arm P, andso as to reach around the rim of the wheel, as shown, is pivoted aframe, extending from the axle M, on one side of the wheel W, to theaxle M again on the other or inside of the wheel W, as shown in thedrawing, plate 1.

To the front end of said frame is attached a chain from one end of thesame, the other end of the same being attached to the hook g. i a

Upon the under side of the frame P is pivoted the bent lever L, uponone, or the shorter, arm of which the framefrests,.so that, by theoperator moving the other arm of the lever, the front end of the frameis raised, and, by means of the chain attached to said frame and saidhook'g, the arm {is also raised, so that the said arm 2' and theflexible bar B may be raised above any obstruction by which it can beinjured.

The flexible bar B may be of any one of those now commonly inuse, as theBuckeye'flexible bar, having the Hussey open guard attached to the same,and the track-clearer attached to the outer end, as now in ordinary use,and operated as above described. 1 i

The machine is made of cast iron, or wrought iron, or of both wroughtand cast iron combined, or of other suitable material.

vThe operation is readily seen from the drawing, motion from the wheelsof the machine W being communicated, through thc wheels D, and pinion O,and crown-wheel a, and. pinion E, and shaft H to the cutters in thefiexiblebar B, said bar being raised by the lever L, and the same beingprevented from rolling over by the hook g.

Constructed as above described, it constitutes a neat and durable mowingand reaping-machine, by means of which grass is more rapidlycut or grainmore rapidly reaped; and the gearing being above the axle, the same isless likely to be injured. i

I claim as new, and desire to secure by Letters Patent-r.-

1. The dome-shaped frame A, in combination with the dome A, and incombination with any mowing and reaping-machinery, substantially asshown and described, and for the purposes set forth.

2. The annular frame 1?, in combination with the frame A and the axle M,substantially as shown and described, and for the purposes set forth.
